RESUMO
La atresia de coanas se caracteriza por la obliteración de la abertura nasal posterior. Es la anomalía congénita más frecuente de las fosas nasales. Tiene una incidencia de 1 cada 5000 a 7000 neonatos, con predominio en el sexo femenino. Puede presentarse en forma aislada o asociada a otros síndromes como el CHARGE (coloboma [C], malformaciones cardíacas [H], atresia de coanas [A], retraso psicomotor y/o en el crecimiento [R], hipoplasia de genitales [G], malformaciones auriculares y/o sordera [E, por su sigla en inglés]). Las manifestaciones clínicas son la obstrucción nasal, cianosis y dificultad respiratoria desde el nacimiento cuando es bilateral. Las atresias unilaterales se caracterizan por insuficiencia ventilatoria nasal y rinorrea unilateral, y pueden pasar inadvertidas. El diagnóstico se realiza mediante endoscopia y estudios por imágenes. El tratamiento es quirúrgico; existen diferentes técnicas y vías de abordaje. Se presenta el caso de un paciente masculino de 7 años con atresia unilateral de coana derecha con resolución microendoscópica, colocación de tutor externo, con buena resolución.
Choanal atresia is characterized by obliteration of the posterior nasal opening. It is the most common congenital anomaly of the nasal passages. It has an incidence of 1 in 5000 to 7000 newborns; predominantly female. It can occur in isolation or in association with other syndromes such as CHARGE (coloboma [C], cardiac malformations [H], choanal atresia [A], psychomotor and/or growth retardation [R], genital hypoplasia [G], atrial malformations and/or deafness [E]. Clinicallypresents nasal obstruction, cyanosis and respiratory distress from birth when bilateral, unilateral atresias are characterized by nasal ventilatory insufficiency and unilateral rhinorrhea, which may go unnoticed. Diagnosis is made by endoscopy and imaging tests. Treatment is surgical, with different techniques and approaches.A 7-year-old male patient is presented with unilateral atresia of the right choana with microendoscopic resolution, placement of an external tutor, with good resolution.

La atresia congénita de coanas se caracteriza por la presencia de placas que obliteran la comunicación entre la cavidad nasal y la nasofaringe desde el nacimiento. Se considera como incompatible con la vida cuando la condición es bilateral. El siguiente es el caso de una paciente femenina, de 17 años, sin síndromes asociados, con obstrucción y descarga nasal anterior bilateral, asociado a respiración oral desde el periodo neonatal. El diagnóstico de atresia bilateral de coanas fue confirmado por medio de endoscopía nasal y tomografía computarizada (TC). La imagen confirmó la presencia de placas atrésicas de composición mixta. La paciente recibió tratamiento quirúrgicamente por vía transnasal con resección de las placas y modelado de neocoana.
Congenital choanal atresia is characterized by the presence of plates obliterating the communication between the nasal cavity and the nasopharynx from birth. If bilateral, this condition is incompatible with life. This following is the case of a 17-year-old female patient, without associated syndromes, with bilateral nasal obstruction and anterior discharge, associated to oral breathing, starting in her neonatal period. The diagnosis of bilateral choanal atresia was confirmed by nasal endoscopy and computed tomography (CT) scan, due to the presence of atretic plates of mixed composition. The patient was surgically treated with plate resection and modeling of a neochoana by means of a transnasal surgical approach.

Nasal obstruction in neonates is a potential fatal condition because of their exclusive nasal breathing. The most common congenital causes include choanal atresia, dermoid cyst, glioma and encephalocele. Choanal atresia is the most common congenital nasal anomaly. When bilateral, it presents with respiratory distress at birth. Unilateral atresia is manifested by respiratory failure and unilateral rhinorrhea, and may go along unnoticed. Diagnosis is suspected in the absence of airfow in the nasal cavity and for the inability to advance a nasogastric tube. Diagnosis is confirmed by endoscopic examination and computed tomography. The definitive treatment is surgical, and there are different techniques and surgical approaches. We describe our experience with 7 patients with this disease, successfully treated by transnasal endoscopic technique.

Amniotic band sequence (ABS) is a group malformation that mainly affects limbs; clinically, constriction rings and lymphedema of the fingers, arms and legs, acrosyndactyly and pseudosyndactyly are observed; also there is congenital amputation of limbs due to distal swelling. Less frequently, craniofacial and trunk involvement are reported in some patients. Etiology is still unknown and most cases are isolated. In this report we present the case of a 45-day-old male with diagnosis of SBA and bilateral choanal atresia as attached finding, and review possible causes of SBA and associated alterations.

La secuencia de bridas amnióticas (SBA) es un grupo de malformaciones de tipo disruptivo que afecta principalmente las extremidades; clínicamente, se observan anillos de constricción y linfedema en dedos, brazos y piernas; pseudosindactilias y acrosindactilias; además, existe amputación congénita de las extremidades por tumefacción distal; en algunos pacientes se han comunicado, con menor frecuencia, alteraciones craneofaciales y del tronco. La etiología es aún desconocida y la mayoría de los casos son aislados. En este informe presentamos el caso de un paciente masculino, de 45 días de nacido, con diagnóstico de SBA y atresia bilateral de coanas como hallazgo adjunto; se revisan las posibles causas del SBA y las alteraciones asociadas.
